Excuse my ignorance, but is this connected with the Dyson equation that relates the Green's function to the self energy, as described in the article for the latter? If so, please explain and change the redirect on Dyson equation to this. If not, please put a note in saying so. Stevvers 03:15, 17 November 2006 (UTC)

I think the articles refered to Quantum action , Schwinger's variational Principle should be also merged into this article about S-Dyson equations. --Karl-H 22:01, 20 November 2006 (UTC)

[edit] Can some background be provided, please?

It would be helpful if this article contained an introduction saying what these equations represent and how they connect to the rest of QFT. —Preceding unsigned comment added by 72.72.65.40 (talk) 22:41, 20 September 2007 (UTC)
